Welcome to guice-persist-orient¶

Main features¶

Integration through guice-persist (UnitOfWork, PersistService, @Transactional)
Support for document, object and graph databases
Database types support according to classpath (object and graph db support activated by adding jars to classpath)
All three database types may be used in single transaction (changes will be visible between different apis)
Hooks for schema migration and data initialization extensions
Extension for orient object to scheme mapper with plugins support
Auto mapping entities in package to db scheme or using classpath scanning to map annotated entities
Auto db creation (for memory, local and plocal)
Different db users may be used (for example, for schema initialization or to use orient security model), including support for user change inside transaction
Support method retry on ONeedRetryException
Spring-data like repositories with advanced features (e.g. generics usage in query). Great abilities for creating reusable parts (mixins). Support plugins.
Basic crud mixins with ability to use object api for graphs
Compatible with Play framework

Note

Orient team tries to move focus from object api (jpa-like) into document and graph apis. Library allows you to use pure document and graph apis, but also provides advanced tools to mix object and graph apis. So you can keep model as pojos and connect them with type safe (also pojo) edges.

Documentation structure¶

Library consists of 3 parts:

Core orient integration (user guide section)
Object schema mapper (mapping section) - used for schema creation from pojos during startup
Repositories framework (repository section) - spring-data like approach of query definitions with annotations

Start reading from getting started guide for introduction.

All core apis are described on API page.
